SKF NKI Series Roller Bearing, 50mm Inside Diameter, 68mm Outside Diameter - NKI 50/25
This roller bearing is a needle roller solution designed for radial load support in rotating assemblies where Compact cross-sections are required. Constructed from bearing steel with a single row of rollers and a sheet-metal cage, it operates with a controlled internal clearance and is suitable for applications demanding defined static and dynamic load capacities and high rotational speeds.
Features and Benefits:
• Needle rollers provide high load support with Compact cross-section
• Sheet-metal cage ensures consistent roller guidance at speed
• CN internal clearance accommodates thermal expansion and shaft fit
• 85 kN static load rating resists Peak stationary loads
• 45 kN dynamic load rating supports sustained rotating loads
• 8,500 r/min limiting speed enables high-speed operation
• Sheet-metal cage ensures consistent roller guidance at speed
• CN internal clearance accommodates thermal expansion and shaft fit
• 85 kN static load rating resists Peak stationary loads
• 45 kN dynamic load rating supports sustained rotating loads
• 8,500 r/min limiting speed enables high-speed operation
Applications
• Suitable for transmissions requiring high radial load capacity
• Ideal for Compact gearbox shaft support arrangements
• Used with precision shafts needing controlled internal clearance
• Can be used for machinery with high rotational speed demands
• Suitable for industrial assemblies prioritising space-saving bearings

What material is used for the rolling elements?
The rollers and rings are MADE from bearing steel.
How does the cage construction affect performance?
The sheet-metal cage maintains roller spacing and reduces skewing at elevated speeds.
What operating condition does the CN clearance indicate?
CN denotes a normal internal clearance suitable for standard operating temperatures and fits.
Which load parameter governs stationary load capacity?
The static load rating of 85 kN defines resistance to non-rotating Peak loads.
What maximum rotational speed should be observed?
The limiting speed is 8,500 r/min and should not be exceeded for reliable operation.
